JAMES DAVIES, OF WEDNESBURY, COUNTY OF STAFFORD, ENGLAND.

DISK WATER-METER.

SPECIFICATION forming part of Letters Patent No. 384,024, dated June 5,1888. Application filed August 3, 1887. Serial No. 246,020. (No model.)Patented in England October 23,1880, No. 13,571.

To all whom it may concern:

Be"it known that I, JAMES DAVIES, ,of

\Vednesbury, in the county of Stafford, Enghave invented certain new anduseful Improvements in Meters for Measuring Water and Gas, which arealso Applicable to Pumps, Blowers, Exhausters, and Engines, (the samehaving been patented in England by Letters Patent No. 13,571, datedOctober 23, 1886;) and I do hereby declare that the following is asufficient description of the invention to enable those skilled in theart to which it appertains to carry the same into practical effect.

Thisinvention relates to that class of rotary meters in which anoscillating disk is employed; and the said invention consists chiefly inan oscillating disk, E, provided with a central ball having a recess inits under side, in combination with a bearing-pin, F, which enters saidrecess and has its point rounded, a lower cone provided with a recesswhich fits said ball, an upper curve, and a cylinder, B, the ballrocking partly on the bearing-pin F and partly on the concave face a, asshown.

The inventionalso consists in the combination of the upper cone and thedisk, having a central ball, either the ball or the cone having a hole,Z, provided with the lower cone, the cylinder having ports b b and thepartition K, as herein described and claimed.

The following drawings will serve to assist the explanation of thedetails thereof.

Figure l is a part section and part elevation of a meter with theregistering train not shown, as it forms no part of my presentinvention. The upper part or cover, A,is asection on line 1 2, lookingin the direction, of the arrow a. (See Fig. 2.) The lower part orcylinder, 13, is a section'on line 5 6, Fig. 6. Fig. 2 is a crosssectionthrough the cover or casing A,looking upward. Fig. 3 is a sectionalelevation of a portion of the upper part, A, on line 3 4 and looking inthe direction of the arrow 1). (See Fig. 2.) Fig. 4 is a cross-sectionof the cylinder B through the division-plate K and looking at thepassages or ports I) and If. Fig. 5 is a section through the cylinder Bat, say, port If, showing how the disk-plate or piston E is placedtherein. Fig. 6 is a plan with the sents a sectional detail view; andFig. 10 an elevation of the division-plate, sliding shoe,

1 and spring.

I make the body or cylinder B of one casting, which enables me to obtainan exact inner working-surface, which is a portion of asphere without abreak or joint; and to overcome the difficulty of placing the disk Einside the cylinder, which is smaller in diameter at b and 11 than atthe center I), and also smaller than the diameter of the disk, I extendone of the passages b Fig.v 4, toward the edge of the casting, so thatthe slot 0' of the disk E, Fig. 5, will pass over, as there shown, toallow the opposite part, e, to pass the end of the body B, when it maybe easily turned into its natural position, as shown in Fig. 1. In thecase of water-meters they would generally be fixed to stand as shown byFig. 1 that is, with the disk E in a horizontal position and supportedupon the small rounded end of the pin F, which enters an outwardlyflaring recess in the ball of the disk. This ball also fits a concaveface, n, formed in the conical end N of the casing. The pin F.1nay beremoved and this concave face a used as the only bearing for the ball.The upper end of the disk-shaft c is provided with a lateral arm, 6 thatenters a recess in the worm-spindle R, which therefore receives motiontherefrom, this motion being transmitted by said wormshai't to theregistering mechanism, as herein after stated. A spring, 6, in thebottom of said recess prevents by its yielding any injury to thedisk-shaft orworm-spindle in case any obstruction gets between the diskand the cones. A division-plate, K, is fixed between the cones a and n,and a slot, e, is cut into the disk D to pass over it. This serves as adivision between the passages I) and b either of which may be inlet oroutlet; but in this case I am treating b as the inlet from pipe L and bas the outlet to pipe Q. Now, as water enters at the pipe L the positionof the disk E is changed,so that its inclined position as now shown iscontinually changed all around the whole circle or cylinder, so that theshaft e is carried around the pin 1", carrying with it the worm-spindleR, which gives motion to the wheel S, which carries the worm-wheel 8,working into the smaller wheel, 8 thus giving very slow motion to thespindle 8 which passes through 'the cover 0?, where it is connected toany convenient kind of registering mechanism,which does not constituteany part of my present invention. By this means the wear upon thespindle s and in the cover or hearing of a will be minimized.

The disk E, I make from vulcanite, compressed paper, or other such likematerial for meters where the temperature of the water or liquids to bemeasured is not high. The outer edges of the disk may have packingplaced in a groove or grooves in its edgesuch, for instance, as shown atFig. 9either in the shape of an elastic ring or rings, or'abestus, orother suitable material,or a number of small grooves may be made toconstitute water-packing, as

' said contents against theball of the disk. Such pressure, if notrelieved, would make the friction too great between the ball and itsupper bearing.

The disks maybe constructed of sheet metal, as shown at Fig. 7, for1ightnessi. e., in two parts made under the stamp or press and thenplaced together. A spring ring havinggrooves cut around its face maythen be inserted, or soft packing. The division-plate K may be madeeither in one piece solid or with an end shoe, k, having a spring, 10which constantly keeps it to a bearing against the center of the diskand the inner part of the cylinder, which are shown in detail at Figs. 9and 10.

What I claim, then, is-

1. An oscillating disk, E, provided with a central ball having a recessin its under side, in combination with a bearing-pin, F,-which enterssaid recess and has its point rounded, a lower cone provided with arecess which fits said ball, an upper cone, and a cylinder, B, the ballrocking partly on the bearing-pin F and partly on the concavebearing-face a", substantially as shown.

2. The combination of the upper cone and disk having a central ball,either the ball or cone having a hole, 2, therein, with the lower (one,the cylinder having parts 11 b and the JAMES DAVIES.
